February 2025 monthly summary for oaknational/Oak-Web-Application: Implemented onboarding terminology update to improve the new-user experience by switching from 'sign in' to 'sign up' in the download/onboarding flow. This involved a codebase-wide refactor of the download flow, renaming components, hooks, and tests to reflect 'sign up' while preserving the core logic that controls the display of download buttons based on authentication/onboarding status. The change is isolated to frontend onboarding and delivers no user-facing behavior changes beyond terminology.
